Author: jkim Date: Thu Jul 29 17:00:41 2010 New Revision: 210617 URL: http://svn.freebsd.org/changeset/base/210617 Log: MFamd64: r210615 Fix another fallout from r208833. savectx() is used to save CPU context for crash dump (dumppcb) and kdb (stoppcbs). For both cases, we cannot have a valid pointer in pcb_save. This should restore the previous behaviour.
